Habits
•Smooth, moderate operation can yield up to 10% savings in fuel.
•Steady speeds without stopping will usually give the best fuel
economy.
•Idling for long periods of time (greater than one minute) may waste
fuel.
•Anticipate stopping; slowing down may eliminate the need to stop.
•Sudden or hard accelerations may reduce fuel economy.
•Slow down gradually.
•Driving at reasonable speeds (traveling at 55 mph [88 km/h] uses 15%
less fuel than traveling at 65 mph [105 km/h]).
•Revving the engine before turning it off may reduce fuel economy.
•Using the air conditioner or defroster may reduce fuel economy.
•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toMaintenance Product
Specifications and Capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle’sscheduled maintenance information.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).

1Add 8 oz. (236 ml) of Additive Friction Modifier XL-3 or equivalent meeting Ford Specification
EST-M2C118–A for complete refill of limited slip axles. Ford design rear axles contain a synthetic
lubricant that does not require changing unless the axle has been submerged in water. Dana rear
axles also contain a synthetic lubricant but do require a change. Refer to yourscheduled
maintenance informationfor change intervals on Dana rear axles.2Add the coolant type originally equipped in your vehicle.3Ensure the correct automatic transmission fluid is used. Transmission fluid requirements are
indicated on the dipstick handle. Check the container to verify the fluid being added is of the
correct type. Refer to yourscheduled maintenance informationto determine the correct service
interval.
MERCON, MERCONV and MERCONSP are not interchangeable. DO NOT mix
MERCON, MERCONV and MERCONSP. Use of dual usage fluids in an automatic
transmission application requiring MERCONSP may cause transmission damage. Use of
a transmission fluid other than the recommended fluid may cause transmission damage.4Service refill capacity is determined by filling the transmission to the bottom of the filler hole with
the vehicle on a level surface. The 6–speed manual transmission is equipped with an in-tank cooler.
Verify the fluid level after operating vehicle to ensure correct fluid level.5Indicates only approximate dry-fill capacity. Some applications may vary based on cooler size and
if equipped with an in-tank cooler. The amount of transmission fluid and fluid level should be set
by the indication on the dipstick’s normal operating range.6Use of synthetic or synthetic blend motor oil is not mandatory. Engine oil need only meet the
requirements of Ford specification WSS-M2C930-A and the API Certification mark.
